NCT05631236 · ACTIVE NOT RECRUITING
Promoting Cognitive Resilience and Reducing Frailty in Older Veterans With Bright Light Therapy
This trial is testing whether wearing light-emitting glasses in the morning — a technique called bright light therapy — can improve sleep, reduce frailty, and support cognitive function in older Veterans. Participants wear the glasses daily for a set period. This is a Phase NA feasibility pilot, meaning researchers are checking whether the study design works and estimating effect sizes before committing to a larger trial. It is not yet testing a proven treatment.
